Pull the fuel line and put the glow starter on and burn up the fuel left in the line,carb, and cylinder.
Just my point, all the fuel in the engine is oil at that point. You start it, run it out, the engine is then running with no oil in it. Thats why all the guys I know that do it are always replacing bearings. The guys that don't do it, don't ever have to replace bearings. Would you run all the oil out of your car when you change it? I hope not. Why run it out of your plane?
I'm not running the motor with no lube. If it doesn't fire it just means that there is no nitro left. "The engine is running with no oil in it". How is it running at all? It won't run with no fuel. No fuel, no heat generated. A car will run with no oil because the fuel is seperate from the oil delivery. You run the motor out of nitro, so it will not run at all.But there is oil left in the crank case and on everything in the motor. Then add the after run to rust proof and keep the castor from becoming gummy after time. My instructor told me to do this and he has motors that are 25 years old and still run without ever changing a bearing. You should see some of these planes. Ancient! But he has always used a castor based fuel. If there is no heat, no damage.
